CLEANSING COMPOUND.

No Drawing.

T 0 all whom z'tmay concern:

Be it known that I, VARREN C. NEWBURY, a citizen of the United States, residing at East Boston, in the county of Suffolk and Commonwealth of Massachusetts, have invented a new and useful Improvement in Cleansing Compounds, of which the following is a specification.

This invention relates to cleansing fluids for softeningand removing gummy, tarry or oily deposits of foreign matter, and for correcting the effect of such deposits upon finished surfaces.

More specifically my inventionis directed to a liquid cleansing compound for use on car bodies and the like, on which deposits of earthy matter mixed with road tar or road oil have been caked so that their removal is diflicult without affecting the finish of the varnish. If allowed to remain the tar or other oily deposit penetrates the varnishand soon eat itsway through thefunderlying coats-of paint, destroying the gloss or finish.

In accomplishing my present invention, I form an oily solvent which forthe purposes ofillustration may be indicated by the following formula: By weight'55 parts of creosote or the like. about parts by Weight of a light lubricating oil such as white loom or spindle oil, and about 10 parts of extra boiled linseed oil, and about 5 parts of oil of turpentine.

The above proportions may be varied, it

being important to maintain a preponderance of the creosote or naphtha and the light petroleum oil. These elementshave a very rapid and efficient action in penetrating and softening the oily or tarry binder of the dirt, and in penetrating the face of contact between the'dirt and the finished surface. At the same time, the other elements have a very eflicient restoring effect for a polished or otherwise finished surface which has been covered by such deposit. Such modifications as are within. the limits of the appended claims are understood to be in accordance with my invention.

What I therefore claim and desire to secure by Letters Patent is:

1. A liquid for removing tar or road oil from finished automobile bodies or the like, comprising creosote in predominating anllount, a light petroleum oil and linseed o1 2. A liquid for removing tar .or roal oil' from finished automobile bodies or the like,

and comprising a creosote in predominating amount, a light petroleum oil, and linseed oil in substantially the following propor-' tions by weight; creosote parts. petroleum oil 30 parts, and linseed oil 10 parts.
